GAS-CHECK.

Specification of Letters Patent.

Patented May 15, 1906.

To all whom it may concern.-

Be it known that I, ALBERT ULLMANN, a citizen of the United States, residing at Macon, in the county of Bibb and State of Georgia, have invented new and useful Improvements in Gas-Checks, of which the following is a specification.

This invention relates to gas-checks; and the object thereof is to provide a gas-check in the manner as hereinafter referred to which is particularly adapted for regulating the flow of gas or for other purposes for which it is found applicable.

The invention further aims to provide a gas-check which shall be simple in its construction, strong, durable, efficient in its use, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel construction, combination, and arrangement of parts hereinafter more specifically described, and illustrated in the accompanying drawings, which form a part of this specification, and wherein is shown the preferred embodi ment of the invention, but it is to be under stood that changes, variations, and modifications can be resorted to which come within the scope of the claims hereunto appended.

In describing the invention in detail reference is to be had to the accompanying drawings, wherein like reference characters denote corresponding parts throughout the several views, and in which Figure 1 is a vertical sectional view of a gascheck in accordance with this invention. Fig. 2 is a detail illustrating the verticallymovable slide for adjusting the pin-valves shown in Fig. 1. Fig. 3 is a detail of the rotatably and eccentrically mounted member for operating the slide. Fig. 4 is a view similar to Fig. 2, showing another form of vertically-movable slide for adjusting the pinvalves, also showing a modified form of valve. Fig. 5 is an elevation showing the adaptation of the gas-check in connection with an inverted light and with means for shifting the eccentrically-mounted member. Fig. 6 is a vertical section of a modified form, and Fig. 7 is a detail of the construction shown in Fig. 6. Referring to the drawings by reference characters, 1 denotes the body of the gas check open at its bottom, as at 2, forming thereby an inlet for the gas, the wall of said opening being screw-threaded, as at 3, to permit of connecting the body 1 with a gas-pipe. (Not shown.) The upper portion of the body 1 of the gas-check is formed in a tapering manner, as at 1, and has the top thereof closed with the exception of a plurality of square openings 5, forming the gas-outlets and through which are adapted to operatethe pin-valves, to be hereinafter referred to.

The body 1 of the gas-check is furthermore provided with an outwardly-extending sleeve 6, forming abearing for an element of the gas check, to be hereinafter referred to.

Arranged within the body 1 of the gascheck and conforming to the interior shape of said body 1 is a vertically-movable slide 8, having its top formed with a laterally-extend ing protuberance, so as to form the upper portion of the slide 8 in a substantially cylindrical manner, as at 9, and the said cylindrical portion 9 has the top edge thereof pro vided with a plurality of tapering pin-valves 10, which are substantially square in cross section. The pin-valves 10 are positioned below the outlets 5 and are adapted to oper ate through the said outlets 5, as well as close the outlets and when operating through said outlets 5 are adapted to regulate the flow of gas. The pin-valves 10 are vertically moved in both directions through the medium of the slide 8, means being provided in a manner as hereinafter set forth for vertically moving the said slide 8, which in turn will carry the pin-valves therewith. The lower end of the slide 8 is provided with a laterally-extending guide member 11., which bears against the inner face of the body 1, provided with an opening 12, which permits of the passage of gas therethrough, and immediately above the said member 11 the slide is provided with a slot 13, in which extends a means for vertically moving the slide to be hereinafter referred to. The end walls of the slot 13 form a stop respectively for the movement of the slide 8 upwardly and downwardly, and there by prevent the pin-valves from entirely leaving the gas-outletopenings on the downward movement of the slide and also prevent the pin-valves from being forced up too high through the gas-outlet openings on the up ward movement of the slide. The slide 8 is furthermore provided near its upper end with a guide 8%.which engages the inner face of the body 1, as shown. The guide 8" is struck from the slide 8, but any other suitable con- 1 of the rod 24 in either direction.

struction can be employed.

Mounted for rotation within the sleeve 6 is a shaft 14, which extends into the body 1 of 5 the gas-check and also projects from the outer end of the sleeve 6, the latter acting as a hearing for the shaft 14. The inner end of the shaft 14 is enlarged, as at 15, and bears at one end against the inner face of the sleeve 6 and I0 at its other end against the slide 8. The enlarged end of the shaft 14 acts as a means i to prevent leakage and also the removal of the shaft 14, and also acts as a means for retaining the slide 8 centrally of the body 1 of 15 thegas-check. The enlarged end 15 of the shaft 14 carries an eccentrically-mounted stud 16, which extends through the slot 13, and when the shaft 14 is rotated the said stud 16 is adapted to shift the slide 8, thereby adjust- 2o ing the pinvalves 10 in one direction or the other in accordance with the direction in which the shaft 14 is rotated. The projecting end of the shaft 14 carries a thumb-piece 17, of non-conductive material. Said thumb- 2 5 piece also acts as a means to prevent the shifting of the shaft 14 longitudinally when the check is set up. It will be evident that when the thumb-piece is grasped by the operator and turned in one direction or the other the 0 stud 16 will cause the shifting of the slide 8,

and thereby vertically move the pin-valves so as to open and close the gas-outlets or to {egulate the flow of gas through the said outets.

In the construction shown in Fig. the vertically-movable slide is indicated by the reference character 18 and carries upon its upper end a circular plate 19, to which is secured a plurality of vertically-extending pin-valves 4o 20, which are cylindrical in cross-section and operated through the as-outlets, but in this instance instead of the gas-outlets being square they are circular. The slide 18 is further provided with a laterally-extending pro 5 tuberance 21 near the top thereof and which acts as a guide, and at the bottom of the slide 18 a laterally-extending guide member 22 is provided, which has an opening 23 to permit of the passage of gas. Immediately above the member 22 a notch 24 is formed in the slide 18, and within the said notch is adapted to operate the eccentrically-mounted pin 16. The construction shown in Fig. 3 is operated in the same manner as that referred to in con- 5 5 nection with Figs. 1 and 2.

In Fig. 5 the gas-check is shown in use in connection with an inverted light," but it is evident that the same can be used with an upright light. The showing in Fig. 5 is for the purpose of illustrating a means for operating the gas-checks when the light is suspended overhead. Said means consists of a bar 25, attached to the shaft 14, and depend ing from the said bar is a pair of chains 26. Stops 27 are provided to arrest the movement w ste The chains 26 can be dispensed with, if desired.

In the modified construction shown in Figs. 6 and '7 the sleeve 6 is dispensed with, and in lieu of the cylindrical shaft 14 a tapering shaft 28 is employed, which extends through the body 29 of the gas-check and carries on its outer end a thumb-piece 30, which is an integral part of the shaft 28 and is separated therefrom through the medium of the neck portion 31, the latter being integral with the shaft and with the thumb-piece. The employment of the tapering shaft 28prevents leakage, and the said shaft 28 on its inner end carries an eccentrlcally arranged stud 32, which engages in the slot of the slide. The shaft 28is retained in position through the medium of the shell 33, which is provided with a keyhole-slot 34 and a swaged portion 35, conforming in contour to the outer end of the shaft 28. Otherwise than that as stat-ed the construction of the gas-check is the same as that shown in Fig. 1, the same reference characters being applied thereto. of setting up the shell 33 so as to secure the shaft 31 in position is as follows: The shell 33 is mounted upon the body 26 of the check and turned until the circular part of the keyhole-slot 34 registers with the opening in the body 29, through which passes the shaft 28. The shaft 28 is then passed through the enlarged part of the keyhole-slot and the opening in the body portion, so that the stud 32 will engage in the slot of the slide. The shell 33 is then turned so that the neck 31 will pass into the small part of the keyhole-slot 34 and until the swaged portion 35 will spring over the outer end of the shaft 28, which securely retains the shaft in position, but permits of the shaft being shifted or partly rotated, so as to impart a vertical movement to the slide 8.

Although in Figs. 1, 2, and 6 of the draw ings the slide 8 is shown as provided with three pin-valves 10, yet it is evident that two can be used or the number of the pin-valves be increased, as desired.

I am aware that a single pin-valve has been employed for regulating the discharge of gas; but in such cases in order that the discharge may be in due quantity the port'or exit opening requires to be made so large that the pressure is insufficient to carry the flame to the top of the mantle of an incandescent or eisbach. burner, nor will the gas discharged through a single center port fill the mantle with a glowing light, which is produced when a plurality of ports is employed. hen a single central valve or handle-valve is employed and other ports or passages are used in conjunction therewith and unprovided with such valves, they soon become clogged by dust or other matter derived from corrosion of the metal, which at first makes the burner unsatisfactory in use and finally entirely useless, since the single opening or eXit,

The manner.

seaese as before stated, cannot furnish sufficient gas to give a satisfactory light. The advantage of a plurality of pin-valves over the construction just set forth is fully described in Letters Patent granted to me November 15, 1904, No. 775,156, upon which the structure herein disclosed is an. improvement. In the structure shown in Letters Patent No. 77 5,1. 56 a vertically-movable screw is employed to operate a plate carrying the pin-valve, the operation being from the bottom of the body of the check and the supply of gas being taken in through the side of the body of the check, whereas in the construction set forth in this application the adjustment of the pinvalves is more readily had, owing to the manner of employing the slide in connection with the eccentrically-mounted operated means therefor, for the reason that by simply imparting a half-turn to the thumbpiece the valves will be moved in one direction and by shifting the thumb-piece a half-turn in another direction the valves will be carried therewith. Furthermore, in the construction embodied .in this application gas is supplied up through the bottom and not through the side of the body of the check, which has been found to be more advantageous. Further advantages of the employment of a plu rality of pin-valves are as follows: impossibility of becoming clogged, a brillianoy of white light caused by proper combustion, the latter being established by the construction of perfect regulation, and securing by perfect combustion economy of the use of gas.

Small bodies are easier and quicker mixed than large ones. Therefore the smaller the exit-openings are the finer the stream of gas will be and the better and quicker it will unite with the oxygen of the atmosphere. The adjustment of the pin-valves insures perfect regulation, no matter what the quality and pressure of gas may be, so that perfect combustion is thereby produced, causing a brighter and whiter light, and there being no waste of gas by smoke economy in the use of gas is established. This benefit is being further enhanced by the annular or square passage of the gas around the pins and which causes the gas stream to be still more thinned out, as owing to the fact that instead of hav ing a solid stream it is a hollow one and which is essentially filled with air as it leaves the outside of the pins.
